I have in quadlock plug (mean block -> Chamber II) at Pin15 reingesteckt the battery wire (yellow) and Pin13 the Zündpluskabel (red).
With newer VW models with CAN bus interface most of Ignition pin (pin 13) has not been established. In addition, it may be that some radios (ISO connector) Ignition and continuous positive need reversed. In this case, may need in ISO plug {Pin4 -> Duration Plus} with {Pin7 -> Ignition} are interchanged.
Caution:
In Quadlock plug on pin 16 in chamber II is VW to a control signal for a possible alarm system, nothing must be reingesteckt !!!!!!
